Abstract. The article considers the current state of tailings ponds at mining and processing plants in the Kryvbas region, provides their parameters and prospects for the use of man-made formations in the form of enrichment waste stored in tailings ponds at mining enterprises. It was established that the formation of man-made deposits involves a process of localization of mineral components, and the localization of useful mineral components can be carried out with minimum energy and material costs.
In the work, the authors consider possible methods for the separation of minerals based on their specific properties, taking into account their further concentration in the process of forming man-made deposits during the operation of tailings ponds.
Based on the results of the analysis and patent search, the authors established the following main disadvantages of domestic and foreign methods for extracting valuable components from the enrichment waste hydro flow with formation of man-made deposits by means of local storage of mineral raw materials separated by their qualitative composition: most of the methods for extracting valuable components from enrichment waste are carried out without account ing the physical and mechanical properties of the particles; the extraction of valuable components from the turbulent flow of the pressure pipeline is carried out by a cylindrical fencing branch pipe, and the significant capital and energy costs are incurred. In addition, it was established that when forming enrichment waste storage facilities, it is necessary to take into account the factor of their possible further development.
It was determined that the most effective method for forming a man-made deposit at dumping enrichment waste by hydrotransportation is to divide it by density by natural gravitational forces for divided damping with preliminary separation of several (two or more) components from the hydro mixture according to the content of useful components, particle size, and density.
Based on the results of the research, the authors of the article propose a method for forming a complex storage facility for enrichment waste combined with a technology for increasing the height of its embankment dams, which ensures the formation of a man-made deposit from the productive part of the hydro mixture and the separate storage of the remaining enrichment waste with rock particles of different qualitative and quantitative composition.
Keywords: enrichment waste, complex tailings storage facilities, separate formation, man-made deposits.
